Referring -first to the more general features of the illustrated embodiment of the invention, the casing 10, whose forward light-exit opening is provided with a lens 11 secured by a bezel 12 isshown as rearwardly terminating in a stepped flange 13, may befreferred to as open at the back except as its'rearward opening is partially closed by a main connecting element 14. Thelatter'is shown as-comprised in an interior organization which is adapted to be inserted through said back opening and to permit attachment of the unit, as by means of'screws 15, to some wall 16,-serving completely toV close said opening. Y v

Tliecasing 10 will be seen interiorly to carry a switch organization, controlled by an operating element 17, which projects throughA an opening in said casing; and the mentioned interiorassembly may include, in addition to the channel-'section element 14 (shown as serving not only for the permanent or removable attachment of the unit butifory various additional purposes), a pair 'of forwardly extending flanges18, 18 respectively carrying, in an vinsulated relationship, both a' longer longitudinally conductive element 19, adapted to connect battery elements 20, 20 in series, and shorter conductive elements 19l and 19, respectively carrying integral and oppositely extending resilient contact lingers .2l and 2l. The formerof these will be seen to be disposed Vfavorably to engagement with an end contact element 22, provided upon a bulb 23; and the latter to be disposed in constant engagement withra fixed contact element 24, comprised in the mentioned switchk organiz'ation.A v Y Y A reflector 25, preferably formed of metal or otherwise rendered conductiveand including a threaded boss within which a threaded neck of the bulb 23 may besecured, optionally by means including a spe@ cial lock nut 26, is shown as pivotally y secured at 27,-adjacent the forward edge of an opening 28 provided in the flange 18. The parallel flange 18 being shown as similarly apertured at 28, cooperating latch and keeper elements 29 and 30 may then be so provided opposite the pivotal connection at 27 as to permit said reflector 25 to be ,y swung forward, v upon a forward, removal yherein used with reference to the direction of light propagation, and not with reference to the position in which a unit of the described character may happen, in a particular instance, to be secured)v the casing 10 and the connecting element 14 may advantageously be provided with some slmple typerof means for releasablyy holding the same in their illustrated relationship. For

example, oneend of 'the' intermediate .web portion of said connectingelement may be 'provided with an-offset and substantially rigidl extension 31', including a reduced terminal tongue 32 which is insertable in a suitable slot o1' opening 33 in the flange 13 of said casing; and the oppositeend of said intermediate web may be integrally or otherwise provided with a resilient clip meml ber 34, so terminally rebent as toE provide a catchelement 35 which is so shaped as to enter a slot 36 in a curved Orother main side or end wall of said-casing and also to provide both ak thumb piece for disengagement of said catch andan inclined guide cam surface 37A Afacilitating engagement thereof upon placement or replacement of said casing.

Anv initial positioning and/or replacement of said casing, and its retention' in a non-rattling relationship to the interior assembly, may be facilitated by the vprovision of rebent and substantially hook-like spac-` ing projections 39 at or near the respective Acorners of. the main connecting element 14,-,said projections being slidably receivable within the flange 13 and. forwardly `engageable with the front wall of the channel provided thereby, Vat times when the` edges of the reflector 25, or its equivalent, Vare in such conductive engagement with flat flange or lens-carrying portion 40 of the front of-the casing 10, as to complete a conductive circuitv (not necessarily including element '14) uponv a" closing ofl the mentioned switch.

referred to,-.with integral tongues 7 4, at its respective corners, each Y tongue extending beyond the edge of -an openingv7lr; but the dimensions/of the card 73-may nevertheless be suchfas to avoid covering any openings 75 or 76 provided for the 'attachment ofk the entire-unit 'to a'wall, as by means of the screws "16. 1 These screwsarev shown as extending through a'pair of symmetrically disposed openings 75, lwhich are disposed on the'shorter diameter of the unit and so formed as to render the removal-ofthe unit dependent upon'the withdrawal of' saidY screws; but the holes 76 will be seen to be of key-hole typeand such that a preliminary lifting as a unit secured byanyscrews eX- tending therethrough enables the'unit to be Vtemporarily removed (for use as a trouble light) without the withdrawalv of' said screws.' l

` It will be obvious that a unit of the described character, when detachably secured, and especially in case itsV dimensions are such that it can be conveniently held in one hand, may be-used in so'mewhat the same generalmanner as an ordinary flashlight; andits. general utility may be further enhanced by the provision of any suitable normally concealed'handle orhandles; For eX- 'ample, to facilitate carrying the' unit in 'the'general manner of a lantern, edge portions of'the flange-13 being struck inward 'as suggested at 77, the substantially parallel deflected portions so provided may be laterally pierced'and shaped suitablyto the reception of hooks or inwardly extending ends 78 upon a bail 79,-shown as so shaped randiproportioned as ynormally to lie in the step provided by the flange 13 although movable to suchafposition as thatsuggested by the dotted lines 7 9. Alternatively or additionally, lugs integral with or adja- 'cent to the spacing 'hooks' or guide fingers 39, interfitting within' the flange, said lugs being inwardly deflected andsuitably apertured, as at 80, may receive inwardly' eX- tending ends 81 of apair ofsymmetric'allyv disposedhandle elements 82, adapted, when inclined or -rounded portions 83 thereofare lifted fromtheir illustrated relationship to the step of flange 13, to be sw-ung-tosuch 4positions'as are suggested at 82and then to be engaged either by the fingers of a user or to receive .a belt, or the like, suitably threaded therethrough and so supporting he unit as to leave the hands vof the user ree. Y y V- The mode of use of the described novel unit being obvious from an inspectionv of the drawing, and the functions served by each of the devices comprised therein having been indicated in connection with the description of the latter, it should be additionally understood not only .that various features of the device might be independently used but also that numerous modifications, additionalA to any suggested herein,- might easily be devised by skilled workers, if informed of the foregoingf-fallwithout departure from the scope of the present invention, as the latter lis indicated above and in the following claims. For example, it will be obvious not only that the contact element 53 may so engage some cooperating contact 53 connected with the reflector as to yavoid 'inclusion of the casing 10 in the light circuit, but also that, whether secured on` said casing or comprised in the interior assembly, a soecalled pull chain switch may be substituted,raccording to the re'- quirements or the tast-e of the user, for the illustrated switch S.
